Statement of Problem: One of the major goals, in most dental researches, is to measure bone destruction or deposition due to the progression or regression of disease. Failure of human eyes to detect minor radiographic density changes resulted in more accurate methods such as optical densitometry and direct or indirect digital densitometry.Purpose: The aim of this study was to determine the accu...
The study was performed in 45 patients with multiple myeloma. There was found significant correlation between diminished bone mineral density of forearm and duration of the disease. No correlation between bone mineral density and biochemical markers of osteolysis (pyridinoline and deoxypyridinoline in urine) and serum levels of cytokines was found.
Renal osteodystrophy is a common finding in patients with renal insufficiency. The maximum of its intensity is found in hemodialysis patients. Bone densitometry is so far the best method for non-invasive assessment of the extent of the illness. Some densitometric studies in hemodialysis patients have already been published but their results differ in prevalence and intensity of renal osteodystr...
STARCH GEL as a supporting medium for the electrophoretic separation of proteins, first used by Smithies (8), has found increased application in recent years (3, 4, 5, 10). However, certain difficulties have become evident in the use of this medium: The optimal resolution of protein components was found to depend on the careful selection of the degree and method of hydrolysis of the starch (5, ...
in this research, the mechanical properties of seven types of nanofilm with differing amounts of silver and silver-clay particles were studied. the elasticity of modulus, tensile strength, toughness, elongation at break, tear strength and color of nanofilms were compared with those of ordinary ldpe film. results showed that the inclusion of nano particles increased the modulus of elasticity, te...
The International Society for Clinical Densitometry (ISCD) periodically convenes Position Development Conferences (PDCs) in order to establish standards and guidelines for the assessment of skeletal health. The most recent Adult PDC was held July 20-22, 2007, in Lansdowne, Virginia, USA; the first Pediatric PDC was June 20-21, 2007 in Montreal, Quebec, Canada. PDC topics were selected according...
This prospective intervention study was undertaken to estimate the prevalence and treatment rate of osteoporosis following osteoporosis screening tests in the same cohort. From November 1, 2014 to August 31, 2015, participants received screening tests for osteoporosis using ultrasound bone densitometry and education concerning osteoporosis and related conditions. The participants were interview...
